Tomato leaves curled up?

[TattyJJ]

I'm not sure if this is normal or not....
On all but a couple of my bigger tomato plants the leaves and stems are curled up quite a bit rather than spread out. It's only at the top of the plant, the stems lower down are quite normal, they are all a nice deep green.
They aren't wilting or anything like that, are getting plenty of sun and were fed last week.

Tried to get a photo to show what i mean, but it's hard to show it.
First pic you can see one of the normal looking ones on the left, but on the right it seems to be tucking under itself

They are fine, mine always do that when growing fast at this time of year.

1 or 2 of mine are doing exactly the same! I'm not worried about it.

Glad you asked as mine look the same and I was getting worried as well

[TattyJJ]

Glad to know they are all ok! I'll stop panicking now

Completely normal. Happens most often in the night when the temps drop. Will straighten out in a few days.

They look really healthy Tatty

Why are you feeding them? They shouldn't need feeding until they have some fruit set. Too much nitrogen can cause the leaves to curl up.

The most likely problem is the temperatures being too variable, not just cold at night but hot in the day. I always have a problem at this time of year because the sun is quite intense and so the temperature in the greenhouse can shoot up but then on days when the sun isn't shining it stays quite cool.

They have been given a weak (half dose) high nitrogen feed to give them a bit of a boost, i was a bit late in the season sowing them and they were only able to get a decent amount of sun when i moved house a couple of weeks ago, they have shot up since.
I'm not planning to consistently use high nitrogen feed, i've read it can give nice big green plants, but with very little fruit.

I'm not worried though, going by the other replies they seem pretty on par with other folk
